Good morning! I am a new pen turner and have only assembled a few Big Bens so far with no issue. I turned one last night and after putting it together it will not extend or retract the refill. The upper barrel will not turn at all. It seems to work fine without the tip on. I've tried another transmission from a different Big Ben kit as well as a different tip and refill with the same results. Any ideas?
Thanks!
Thanks!
